Which type of Thyroidectomy requires lifelong hormone replacement therapy?

A total thyroidectomy involves the complete removal of the thyroid gland. Since the thyroid gland is responsible for producing hormones that regulate metabolism, heart rate, temperature, and other bodily functions, its removal leads to a deficiency in these hormones. Consequently, patients who undergo a total thyroidectomy will require lifelong hormone replacement therapy to compensate for the loss of hormone production and maintain normal metabolic and physiological functions.

In contrast, a subtotal thyroidectomy preserves some thyroid tissue, which may allow for sufficient hormone production, potentially reducing or eliminating the need for replacement therapy. Laparoscopic and conventional refer to the surgical techniques used for the procedure, not the extent of thyroid hormone preservation. Hence, the necessity for lifelong hormone replacement therapy is specifically associated with a total thyroidectomy.
